Y acid, or the like, Ienters through pipe 13 and body 19 is provided with the passage jl1, conpasses into standard 11 and through pipe 15 trolled by valve 18, which first extends hori- J into valve chamber 17, where its outlet is conzontally into the center of the body and then trolledby gas valve 18. Valve chamber 17 continues vertically downwards through the 50 forms the portion of body 19 which is held center thereof. The end portion of the ver- 100 Ill) passes through tube tical passage is threaded, and attached to the threaded portion is a tube 42 extending downward into the liquid contained in bottle 32.

Another passage is formed in the body and clearly seen in Figure 3 at 43. This passage runs partially horizontally and partially' vertically upwards and is controlled by re lease valve 44. To the threaded vertical portion of the passage is attached a vent or release tube 45 which extends into the cap 26 of cylinder 25. There is another vertical passage provided through body 19 and indicated at 46. This passage communicates between bottle 32 and cylinder 25.

The top portion of this passage is provided with a seat for a check valve or ball, indicated at 47, which prevents liquid from leaving c linder 25 when bottle 32 is removed from t e machine. Ball 47 is housed in a cage, indicated at 48, to prevent the ball from displacement and keeping it constantly in its seating position.

When gas is supplied through valve 18 and 42 into the container, the

quid therein will rise and some of it will pass through passage 46 into cylinder 25. In passing, thus, the liquid has to litt ball or check valve 47, which immediately seats itself when the pressure from below ceases. Thus, when the liquid in the container is suiciently charged and then the bottle is removed, no liquid contained in the cylinder 25 is rmitted, due to check Valve 47, to spill or otlirwfse leave the cylinder. y

When the liquid in the cylinder reaches such a height that it would pass down through exhaust tube 45, when valve 44 is operated, it becomes necessary to release the liquid from cylinder 25, which is done by means of valve 49, seen in Figures 1 and 2. This valve is connected by means of a passage 5() running partially horizontally and partially vertical, and terminating at the bottom of the hollowed-out portion of body 19, ,which portion communicates with cylinder By preventing the spilling andwaste of the liquid, my device becomes not only more economical, but more practical and cleaner in operation.

Operation The use of my device is rather simple; pipe 13 is connected to a bomb or container filled with gas with which a liquid or beverage is to be charged. A number of bottles are filled with the beverage and successively clamped into position by means of first releasing and then elevating table 32, by turning the hand Wheel 35. Vhen the bottle is in place and tightly presses with its neck portion against rubber cushion 30, valve 18 is Opened and the charging gas is permitted to venter the liquid through pipe 42 extending `into the bottle.

When the gauge indicates a sufficient pressure considered sate as to the tensile strength of the container, valve 18 is closed. Before removing bottle 32, valve 42, which releases the gas from cylinder 25 through pipe 45, is opened. Now the bottle is removed and another bottle inserted in its position. After a period of thus charging the liquid of numerous bottles, the excessive liquid gathering in cylinder 25 is released by means of valve 49.

Having thus described my invention, be it understood that while I have shown specific constructions in the drawing, that changes and improvements may be imparted therein Without deviating from the 'broad scope of my invention, for which I claim:

1. A liquid aerating device, comprising in combination, a base, a hollow standard extending therefrom, a pipe connection leading into said standard, a control body associated with the upper portion of said standard and containing a gas intake passage, a gas outlet passage and a liquid discharge passage, all of said passages provided with' control valves, a through passage transversing the body in substantially vertical direction and provided with a check valve for preventing liquid from passing downwards through the body while permitting it to pass upwards, a cylinder mounted on top of the body and provided with a gas pressure indicating gauge, a resilient container seal provided at the bottom of said body, said gas intake pas- Sage having a connection with said hollow standard, a charging pipe extending from said intake passage downwardly through said container seal and adapted to enter a container placed into the device, a gas discharge pipe connected with and extending from said gas discharge passage into the upper portion of the interior of said cylinder, said liquid discharge passage connecting with the lower cylinder portion, a container supporting and locking table adjustably associated with said hollow standard, means for raising or lowering said table provided with the latter, and an adjustable screen or safety guard associated with said hollow standard and adapted to house a container placed upon said table.

2. In a liquid aerating device, the combination with a base, of a hollow standard extending therefrom and adapted for conveying gas, gas intake means provided at one end of said standard, gas discharge means secured at its other end, gas and liquid control means connected with said discharge means and removably associated with said standard, and adjustable container supporting means removably and adjustably mounted with said standard and adapted to facilitate pressing a container, the content of which is to be aerated, against said gas and liquid control means.

3. In a liquid aerating device, the combination with a base supported, hollow standard, of gas and liquid control means adjustably mounted upon said standard and connected with its hollow interior, said control means comprising a body provided with a valve controlled intake passage adapted to convey gas into a container, the content of which is to be charged, a liquid retaining cylinder connected with said body, a valve controlled passage provided in said body and extending into said cylinder and adapted to release excess liquid from such container into the cylinder, a valve controlled gas discharge passage provided in said body and connected with the upper portion of said cylinder, and a n valve controlled liquid discharge passage connecting with the lower portion of said cylinder.

In testimony whereof I aiiX my signature.
